More Information about Termites in Montana
According to Termite Infestation Probability Zones (TIP Zones), portions of Montana are located in TIP Zone #3 (slight to moderate), which means there is some potential for damage by subterranean termites. Areas with lower probabilities for activity require fewer termite control measures to meet International Residential Code building standards for new homes than areas with more frequent activity.

Although drywood termites are not established in Montana, it is possible for this species to travel in wooden objects, such as furniture and wine crates, and establish colonies in the state. Drywood termites have been found in areas far from their native habitats. A licensed termite inspector can help identify species not native to the state.

In states like Montana where termites are active, it is essential to maintain an effective termite prevention and control program. If you own a home in Montana, talk to your termite control expert about methods to help protect your home from termite infestations and damage.
